Major Agronomic Practices3MAJOR AGRONOMIC PRACTICESSUMMARYA few general rules for good agronomic practices are:l Select a variety suitable for your climate/environmental conditions, possiblywith resistance against pest(s) or disease(s).l Use clean seed, and/or clean planting material.l Add lots of compost (or other decomposed organic material) to the soil everycropping season, both to nursery sites and to the main field.l When a lot of organic material is used, use low amounts of chemical fertilizers.l Practice crop rotation to the main crop families.l Practice proper sanitation by removing and destroying all crop left-overs atthe end of the season.Cabbage Ecological Guide - 200010
